The port 4040 is *not* used. No process is listening on 4040. As per the logs, 8080 is used for WebUI. The log mentions the below
16/02/19 03:07:32 INFO Utils: Successfully started service 'MasterUI' on port 8080. 16/02/19 03:07:32 INFO MasterWebUI: Started MasterWebUI at http://127.0.0.1:8080 However I am not able to see any UI, when I point the browser to http://127.0.0.1:8080 The browser just hangs.
